find strings in listbox

[soryjero]

hello,

 

i am trying to find indexes of items from a string.

 

i introduce a string in a textbox and click on a search button which has this function:

listBox1.FindString(textBox1.Text)

but with this, i only get first index.

 

how could i do to get all indexes?

 

i have tried

int[] idxs = listBox1.FindString(textBox1.Text)

but idxs is array type and listBox1.FindString(textBox1.Text) is int type, so i get an error.

 

could anyone help me please?

 

thanks in advance.
